摘要
循环水水产养殖系统中产生的残饵、粪便等固体废弃物的处理是实现水产养殖污染零排放的核心技术之一。随着环境法规的完善,政府将逐步要求养殖单位在养殖系统内部对固体废弃物进行处理,已报道的处理方法有堆肥、掩埋等。概述了循环水养殖系统中固体废弃物处理的研究进展,重点介绍循环水养殖系统固体废弃物厌氧消化处理技术的现状及存在的问题,并讨论应用人工湿地法、生物絮凝技术处理水产养殖固体颗粒物的研究状况。
The treatment of waste solids in terms of uneaten feed and excreta which stemed from recirculating aquaculture system （RAS） is one of the core technologies to realize the aim of zero emission for the aquaculture pollution. With the perfection of environmental regulations, it is impelled to treat the waste solids within the aquaculture units. The covered solids managements include composting, landfill and so on. The current review summarized the research progress on the treatment of waste solids steming from RAS, and emphasized on the treatment status and exsiting problems of anaerobic digestion applied in waste solids from RAS. The other applied methods such as created wetlands, bio-flocs technology were also discussed.
